1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC, EDAC or EDCI) is a water-soluble carbodiimide usually handled as the hydrochloride. [1] It is typically employed in the 4.0-6.0 pH range. It is generally used as a carboxyl activating agent for the coupling of primary amines to yield amide bonds.
Another common example is the reaction of a primary amine or secondary amine with a carboxylic acid or with a carboxylic acid derivative to form an amide. This reaction is widely used, especially in the synthesis of peptides. On the simple addition of an amine to a carboxylic acid, a salt of the organic acid and base is obtained.
In chemistry, ammonolysis (/am·mo·nol·y·sis/) is the process of splitting ammonia into + +. [1] Ammonolysis reactions can be conducted with organic compounds to produce amines (molecules containing a nitrogen atom with a lone pair, :N), [2] or with inorganic compounds to produce nitrides.
In this example, the second reactive group (amine/acid) in each of the starting materials bears a protecting group. In organic chemistry , peptide synthesis is the production of peptides , compounds where multiple amino acids are linked via amide bonds, also known as peptide bonds .
One example is Kapton where the repeat unit consists of two imide groups derived from aromatic tetracarboxylic acids. [3] Another example of polyimides is the polyglutarimide typically made from polymethylmethacrylate (PMMA) and ammonia or a primary amine by aminolysis and cyclization of the PMMA at high temperature and pressure, typically in ...
A diamine is an amine with exactly two amino groups.Diamines are used as monomers to prepare polyamides, polyimides, and polyureas.The term diamine refers mostly to primary diamines, as those are the most reactive.
The first example of a palladium catalyzed C–N cross-coupling reaction was published in 1983 by Migita and coworkers and described a reaction between several aryl bromides and N,N-diethylamino-tributyltin using 1 mol% PdCl 2 [P(o-tolyl) 3] 2.
1-Ethyl-3-methylimidazolium chloride or [EMIM]Cl is an ionic liquid that can be used in cellulose processing. [ 1 ] [ 2 ] The cation consists of a five-membered ring with two nitrogen and three carbon atoms, i.e. a derivative of imidazole , with ethyl and methyl groups substituted at the two nitrogen atoms.
